I have been working on small jobs for this bike while waiting on the chrome work to return.  I am not sure why but had to trim the length of my spokes to work with my Worksman wheels. Then rethread.  The front wheel is complete and I can put the tire on it now.  But still waiting for the rear hub to come back. I am also waiting on the seat pan. (and many other parts) I am planning on just doing the leather work myself. But, if not, there is a local leather shop in town to bail me out.  He did the seat on the Servi-glide.

I had already had the exhaust manifold chromed.  Then decided to run a dual exhaust that I have been saving. It was then that I noticed it goes over the manifold NOT inside.  I put some elongated holes in a 1/4" thick plate and bolted the manifold to it.  This allowed me to indicate it in, so it was perfectly vertical in both directions.  Then I found the center of the outlet, gave the mill a few dimensions as a circular profile.  This allowed me to interpolate the hole.  Depending on what side of the circle I put the cutter on dictates if it will mill the I.D. or the O.D.    By telling the mill the radius and the size of the cutter the CNC does the rest. 
 I set the outer diameter at 1.420".  It slips into the exhaust quite nicely!

Wayne Mahaffey is currently trying to find a guy to make more reproductions. The last guy that made them is no longer willing to make any more. I'm also on the hunt for one.

Looking for a complete engine, magneto, and carburetor for a 1936 Simplex Servi-Cycle. If anyone has any leads, please let me know. Thanks!

I wonder what the sign in front of it says. Looks like it says Chief on it.

Rick ,
